What are we talking about?

SNMP(Simple Network Management Protocol)

Why we chose Python

Simply ....Simple Network Management Protocol

Where did it come from ?

– Internet Engineering Task Force(IETF) »Network Management Area

What is it ?

more than just a protocol …

It defines an architecture for extracting information from the network regarding the current operational state of the network,using a vendor-independent family of mechanisms

Structure of Management Information (SMI)

identifies and defines structure of management information

– RFC1155 defines

– commonly defined data item

– syntax of the data type

– semantics of the data object

Version

Two major versions SNMPv1, SNMPv2

SNMPv1 is the recommended standard

SNMPv2 has become split into:

SNMPv2u - SNMPv2 with user-based security

SNMPv2* - SNMPv2 with user-based security and additional features

SNMPv2c - SNMPv2 without security

Syntax uses ASN.1 (Abstract Syntax Notation)

– binary encoding

02 01 06is a 1 byte integer, value 6 Primitive Types

INTEGER, OCTECT STRING, OBJECT IDENTIFIER, NULL

Syntax

Defined Data Types

IpAddress what you expect

Counter non-negative integer

TimeTicks time in hundredths of seconds

SNMP TREE

MIB

Management Information Base (MIB)

– "database"of network objects

– Groups » System, Interfaces,IP, TCP,

– "Access" and "Status" attributes

– actual variables are "instances" of OIDs

eg .1.3.6.1.2.1.1.1.0 sysDescr.0

SNMP

The SNMP protocol itself

– allows inspection and alteration of MIB variables

UDP Based

– not acknowledged transactions

PUT, GET, GET-NEXT operators

WHY WE USED PYTHON

Productivity!

Reduced development timecode is 2-10x shorter than C, C++, Java

Improved program maintenancecode is extremely readable

Less training language is very easy to learn

What is it used for?

web scripting

ad hoc networking programming

XML parsing

database applications

GUI applications

Network Tracker and Poller

Working Details• Configure snmp agent in each node

• Then enable snmp and snmpd in every node

• Query snmp agent to get required details

• Response from each agent is sent to the manager(GUI)

Language Overview

• Language used is Core Python

• Designer Used

Qt Designer and PyQt

• Modules of Python used cmdgen from rfc3413.oneliner

QtGui from PyQt4

GUI Designer

• GUI Designer used is Qt 4 Designer

• Qt (Cute) is cpp based designer tool

GUI can be designed using Qt and it is then converted into any programming language

Here language is python and compiler used in pyuic

Output

• System Description

System Name , System Uptime,

• Interface

No of interfaces , List and Status of Interfaces

• Ip Configurations

Ip forwarding status , Error status
